Specific implementation mode
Technical scheme of the present invention is described in further detail below in conjunction with description of the drawings and specific embodiment.
Referring to Fig.1, the processing method that a kind of arc board group of the invention closes size, is specifically implemented according to the following steps：
First, in the first clamping of one end of each arc plate processing position, the other end then processes the second clamping position, and works as
After all cylinder assemblings of arc plate, all first clampings position constitutes the first cylindrical end, and all second are clamped position then structure
At the second cylindrical end；
Secondly, after the cylinder assembling of all arc plates being formed sub-assembly 2, the first circle is clamped using cramping body 1
Post ends, and the second cylindrical end is fastened in the blind hole 301 of 3 side of top plate；
Finally, the sub-assembly 2 after being clamped by aid body 1 and top plate 2 is packed into lathe, setting radian is carried out to its surface
External cutting.
It should be noted why selecting to process one first clamping position, the other end in one end of each arc plate
The design method of one second clamping position of processing, on the one hand can facilitate after the cylinder assembling of multiple arcs plate, to combination
Part 2 is clamped, and on the other hand compared with the mode for processing retaining part directly on sub-assembly 2, the difficulty of processing also obtains
To greatly reducing.
As shown in Fig. 2, being provided with ring-shaped step in the first cylindrical end, the side of cramping body 1 is pressed on ring-shaped step.
Ring-shaped step in first cylindrical end, i.e. small one and large one two outer circle, clamping part of the small outer circle as cramping body 1
Position, large cylindrical then as processing when centering benchmark, the side of requirement clamping body 1 need to abut against when 1 clamping assemblies 2 of cramping body
At ring-shaped step, prevent sub-assembly 2 from larger bounce is axially occurring.
As shown in figure 3, cramping body 1 includes upper clamping piece 101 and lower clamping piece 104, upper clamping piece 101 and lower clamping piece
104 are fixedly connected by one or more pairs of bolts 103.
The clamping mode of cramping body 1 uses the structure of multipair bolt 103, each pair of by two bolts 103, two nuts, two
A locking nut and two washer compositions, cutting speed when specific logarithm can be according to the weight, size and turning of arc plate
To determine.
As shown in figure 4, the side edge of top plate 3 is evenly equipped with multiple screw holes, Screw assembly has adjusting bolt in each screw hole
303, when sub-assembly 2 is locked in the blind hole of top plate, the lower end of each adjusting bolt 303 withstands on the side of the second cylindrical end
Portion.
Top plate 3 is in the second cylindrical end of sub-assembly 2, it is desirable that the length of the second cylindrical end of sub-assembly 2 is necessary
More than the depth of the blind hole 301 of 3 side of top plate, so that the end face of sub-assembly 2 can be close to the inner stopper end face of top plate 2, simultaneously
Centering benchmark when exposed periphery can be as processing, facilitates sub-assembly 2 before turning to the machined alignment in workpiece both ends
Outer circle carry out centering, each arc plate can be finely adjusted by adjusting bolt 303, it is ensured that machining accuracy.
As shown in Figure 3 and Figure 4, the outside of cramping body 1 and the outer of top plate 3 are both provided with one or more hanging rings 102,
The movement of cramping body 1 can be realized by hanging ring.
As shown in figure 5, being provided with centre bore 302 at the center of top plate 3, centre bore 302 is connected with close to the other side of top plate 3
Bellmouth.
It is provided with centre bore 302 in top plate 2, arc-shaped workpiece is ensured by the verticality of control centre hole 302 and bellmouth
With the positional precision between machine tool rotary center, the verticality between the bottom surface of inner stopper and the conical surface of bellmouth is generally required to exist
Within 0.02mm.
In an assembling process, it is desirable that sub-assembly 2 is put into the blind hole 301 of top plate 3 first, is aligned manufactured outer circle
Face and end face compress each arc plate with adjusting bolt 303, then cramping body 1 are clamped in the other end of sub-assembly, cramping body
1 is adjacent to having added at ring-shaped step of sub-assembly 2, then compresses sub-assembly 2 with bolt 303, nut, locking nut and gasket and lock
Extremely, upper lathe process, when turnery processing with sub-assembly 2 be clamped one end ring-shaped step outer circle and 3 one end of top plate it is manufactured
Outer circle is as centering benchmark, and the adjusting bolt 303 in top plate 2 is used for finely tuning arc plate, during lathe centre is held out against in top plate
At heart hole 302, the clamping, centering and adjustment to workpiece are realized.
Therefore, the processing method that arc board group using the present invention closes size, together by multiple arcs plates assembled
When size, interrupted cut, bias that single processing arc-shaped workpiece work in-process is formed are can avoid, there is bright seam crossing after assembly
Situations such as aobvious boss and irregular outer circle, occurs, while in such a way that flexibility positions, it being made to be not only suitable for rigid material
Suitable for fragile material, both it had been applicable in and has been also applied for large-scale workpiece with miniature workpiece, clamping workpiece when solving overall package processing
The problem of difficult, influence product quality such as centering is difficult, yielding, low production efficiency, fragile material are easy to crack.
